All eukaryotic cells share some characteristics Biology essay
An organelle is a compartment within a eukaryotic cell that has a specific function. The name 'organelle' comes from the idea that these structures are to cells what an organ is to the body. Normally, organelles are enclosed in their own lipid bilayers. They are essential for various cellular functions, including energy production. Plant and animal cells are both eukaryotic cells, meaning they possess a defined nucleus and membrane-bound organelles. They share many common features such as a cell membrane, nucleus, DNA and organic chemical with a complex molecular structure found in all prokaryotic and eukaryotic cells. It encodes genetic information for the transmission of hereditary traits. The structure of DNA was described, leading to a better understanding of DNA replication and hereditary control of cellular activities. Fungi are eukaryotic organisms, i.e. their cells contain membrane-bound organelles and well-defined nuclei. However, historically, fungi were included in the plant kingdom because fungi lack chlorophyll and are distinguished by unique structural and physiological features, that is, components of the cell wall and cell membrane. Although both cell types share some common features, eukaryotic cells are more complex. Distinguishing features that define eukaryotic cells include: All eukaryotic cells have a separately enclosed nucleus within the cell's cytoplasm. Mitochondria exist in some form in the nucleus of the eukaryotic cell. The term 'eukaryotes' is derived from the Greek words 'eu', meaning 'good', and 'karyon', meaning 'kernel', meaning 'true nuclei'. The eukaryotes are thought to have originated from the prokaryotes, roughly cell, in biology, the basic membrane-bound unit that contains the basic molecules of life and of which all living things are composed. A single cell is often a complete organism in itself, such as a bacterium or yeast. Other cells acquire specialized functions as they mature. These cells work together with other specialized cells,
